Finished riveting the tailcone. Did the #1 crosstie, and the upper crosstie box, then riveted in the shear web/aft bulkhead assembly. The tailcone is now complete. The Upper longeron is not yet riveted to the skin, so that the Turtledeck can be installed. Also the lower horizontal splice plates are not yet riveted/bolted, per plans (that will happen when fore/aft fuselage sections are mated). I also left the vertical stabilizer spar channel unriveted, as it might make things easier to get to later.
